BGFX now works on Steam Deck.

How it works
Install Borderless Gaming from Steam, open the app, pick a game, choose your effects. Borderless Gaming installs a Vulkan layer that hooks into your games automatically — you launch games the way you always do, from Steam, and the effects are just there. No desktop mode, no scripts, no extra software. Your presets are saved per game. Set it once and forget about it. One thing I keep seeing asked: you do not need to launch games through Borderless Gaming. Just configure your effects and launch your game normally.
Built for Game Mode
This is a new app written from scratch for SteamOS — not a port. I recreated Valve's Holo design language so it looks and feels like part of your Deck. Full gamepad nav, L1/R1 tab switching, the native on-screen keyboard, audio feedback on every action. [previewyoutube="Xr346asHdUA;leftthumb"][/previewyoutube]
Tweak effects while you play
Press Left Stick + Right Stick + R1 and an overlay slides in from the right. Adjust any parameter in real time — sharpening strength, upscaler settings, swap entire presets — without leaving your game. The overlay blocks game input while it's open, so you won't accidentally move your character while tweaking a slider. [previewyoutube="Z4g5ZlsaaYw;leftthumb"][/previewyoutube]
Lightweight
The entire effect pipeline runs on the GPU. Effects operate directly on frame data — no copies to system memory, no CPU involvement. Shaders compile in the background so your game is never interrupted. [previewyoutube="Eiaqu1wT86o;leftthumb"][/previewyoutube]
Scaling modes
Five scaling modes per effect in the chain:

Fit — Scales to fit with letterboxing, keeps aspect ratio
Fill — Scales to fill the screen, may crop edges
Integer — Pixel-perfect 2x, 3x scaling, great for retro games
Stretch — Fills the screen exactly, may distort
Auto — Picks the best mode for you
The output scaler adapts automatically — sharp bicubic filtering when downscaling, smooth bilinear when upscaling.
Windows improvements
Windows gets a big update too. There's a new Vulkan effects backend that runs the full effect chain through Vulkan alongside D3D11 capture — if your driver supports it, the handoff happens entirely on the GPU with no CPU wait. The D3D11 renderer has been rewritten for lower GPU load, with fixes for frame safety during live scaling changes and better signal handler coexistence with Wine/Proton. Open the overlay on Windows with Ctrl+Shift+F12. Also works with a gamepad.

All of the changes below are for BGProxy.
Misc Fixes
Fixed input issues introduced in the previous update. The mouse cursor should now work in Dishonored and other Unreal games again.
Fixed some minor render issues.
GPU spoofing
You can now make games think you have a different graphics card. Some games won't launch or will disable features if they don't recognize your GPU; this gets around that. Add a Spoof section to your bgproxy.ini (details below).
[/hr]
OpenGL on DX12
OpenGL games now present through a DirectX 12 pipeline. Best case is zero-copy via a shared texture, otherwise it falls back to async or synchronous readback depending on driver support.
OpenGL contexts are automatically upgraded to the highest compatibility profile your driver supports, which lets the driver apply more optimizations while keeping legacy rendering working.
Frame latency waitable is now waited on before rendering instead of after, which fixes cases where the game could start drawing before a back buffer was available.
[/hr]
Timer and sleep fixes
All on by default, no config needed.
Games using Windows wait timers get ~0.1ms precision instead of the default 1–16ms. Needs Windows 10 1803+.
Old multimedia timer calls are also upgraded to Windows 10 high precision timers.
Some games sleep their render thread between frames, which causes micro-stutter. BGProxy now intercepts these fix them.
[/hr]
Other
Device loss now logs the specific HRESULT from GetDeviceRemovedReason.
Proxy DLLs set a window property identifying which proxy type is loaded, so external tools can check without inspecting the file.
[/hr]
bgproxy.ini configuration
Place a file called bgproxy.ini in the same folder as the proxy DLL. If you don't create one, defaults are used.

Background Behavior
All games now continue rendering and playing audio when alt-tabbed.
Keyboard and mouse input is blocked while the game is in the background, so you can type in other apps without affecting the game. Gamepad input still passes through.
Tabbing back into a game no longer leaves keys in a pressed state.
[/hr]
Stability
Fixed crashes on startup for Yakuza 0, Metro 2033, Fallout: New Vegas, and others.
[/hr]
Rendering
Fixed the "wavy" / shimmering motion artifact at native resolution in Dishonored.
Anti-aliasing and color accuracy are now preserved in games that use MSAA or sRGB when using flip model presentation.
Major performance improvement for OpenGL games (KOTOR, StarStable Online, etc.) — rendering no longer goes through the CPU.
[/hr]
Improved Proxy Detection for Unity & Custom Engines
[/hr]
Previously, the installer only checked for graphics DLLs through static PE import analysis. Engines like Unity and Unreal load D3D and OpenGL dynamically rather than through static imports, so the analyzer would find no available proxies for these games. The installer now properly supports these engines. This means the correct proxy is detected and offered automatically, even for engines that load their graphics APIs at runtime.

For years, Borderless Gaming has helped thousands of you wrangle stubborn games into borderless windowed mode. But there have always been two classes of games we've struggled with. The first: games with no windowed mode at all. Classic OpenGL games, older DirectX 8/9 titles, and even some modern DX11 games that change your desktop resolution and take over your entire screen. Without a window, Borderless Gaming had nothing to work with. The second: games that technically have a window, but fight you every step of the way. Older OpenGL and DirectX games that break, flash, or refuse to render properly when their window is moved or resized. This is why Borderless Gaming has accumulated dozens of profile options — delay timers, style overrides, resize workarounds — all to deal with games that don't cooperate. Even with all those options, some games just won't behave. Today, that changes.
Introducing BGProxy
BGProxy is a new feature that intercepts a game's graphics pipeline and converts fullscreen-only games into normal, resizable windows. It supports OpenGL, DirectX 8, DirectX 9, and DirectX 10/11/12 (via DXGI) — covering everything from early 2000s classics to modern titles. Star Wars: Knights of the Old Republic (OpenGL) — no native windowed mode, now running in a resizable window via BGProxy.
[/hr]
What's Different From Classic Mode?
Previously, Borderless Gaming could reposition and resize a game's existing window, but the game still rendered at its original fixed resolution. BGProxy patches the rendering pipeline directly — and what that means depends on the graphics API: DirectX 8, 9, 10, 11, and 12 games get their presentation parameters rewritten on the fly. BGProxy forces the game into windowed mode and upgrades the swap chain to use modern FLIP model presentation, which reduces latency and improves frame pacing. The game actually renders to fit your window — drag the border, maximize, span ultra-wide across all your monitors, and the game re-renders at that resolution in real-time. OpenGL games work differently — the GL backbuffer can't be resized after creation. Instead, BGProxy captures the rendered frame and scales it to your window using high-quality interpolation. The result is a clean, smooth image at any window size, even when stretching a 640x480 game across a 4K display. For older games running at low native resolutions, this scaling makes a visible difference. Instead of blocky nearest-neighbor upscaling, BGProxy uses halftone filtering that smooths the image and produces a noticeably better picture on modern high-resolution displays. For even higher quality, pair it with BGFX and apply real-time upscaling effects like FSR, CAS, and more. Borderlands — drag the border to any size and the game renders to match.
BGProxy also makes games behave like proper desktop applications:
Alt-tab without pausing — The game always thinks it has focus, so it won't pause, mute, or drop to a menu when you switch windows
Full window controls — Minimize, maximize, resize, move between monitors
Input isolation — Keyboard, mouse, and controller input is suppressed when the game is in the background
Mouse coordinate scaling — Input stays accurate at any window size
Once BGProxy gives you a window, Borderless Gaming does the rest — borderless fullscreen, custom positioning, ultra-wide spanning, automatic profiles. You can also combine BGProxy with BGFX to apply real-time upscaling and post-processing effects on top of the windowed game. They're all designed to work together. Star Stable Online (OpenGL) — forced into windowed mode with BGProxy.
[/hr]
Under the Hood
BGProxy analyzes your game's executable to determine its graphics API, then places a small proxy DLL in the game directory. When the game launches, it loads the proxy instead of the system graphics library. The proxy forwards normal calls through to the real DLL, but intercepts key operations:
Fullscreen display mode changes are caught and redirected into a window
DirectX swap chains are upgraded to FLIP model presentation for lower latency and smoother frame pacing
OpenGL framebuffers are captured and scaled with high-quality filtering to any window size
Game-originated window management calls (resize, move, style changes) are blocked to prevent the game from fighting windowed mode
Focus and activation messages are spoofed so the game never detects it lost foreground
DirectInput and XInput are filtered when the window is in the background
Borderless Gaming automatically detects the correct architecture (x86, x64, or ARM64) and graphics API from the executable — you don't need to figure out which proxy to use. Constructor — running in a proper window via BGProxy.
[/hr]
How to Use BGProxy
Launch the game once so it appears in Borderless Gaming's window list
Right-click the game and select "Install BGProxy"
Restart the game — it will now start in windowed mode
Make it borderless using Borderless Gaming as normal, or set up a profile
To remove it, right-click the game and select "Uninstall BGProxy". Borderless Gaming will close the game and cleanly delete the proxy. LEGO City Undercover — forced into windowed mode, ready to go borderless.
[/hr]
Important Notes
Anti-cheat — BGProxy places a DLL in the game directory. Some anti-cheat systems may flag this. We recommend using BGProxy with single-player and offline games only.
Compatibility — While we've tested extensively, some games may behave unexpectedly. You can always uninstall with one click to return to normal - but let us know if in the Discord if you run into problems with a specific game.
Restart required — The game must be restarted after installing or uninstalling BGProxy.
[/hr]
BGProxy has been a long time coming and we think it's going to make a real difference for the games that needed it most. If you run into issues, let us know in the discussions. Happy gaming!

New Features
Slang-based BGFX - Effects now use Slang as the shader foundation, enabling cross-platform support for the upcoming SteamDeck and Linux release.
DX12 Renderer - DirectX 12 is now available and being A/B tested. If you experience issues, launch with
--no-dx12
to use the DX11 pipeline.
Profile-Guided Optimization - Effect compilation now uses PGO for your GPU rather than trying to be one-size-fits-all, so system resource usage at runtime has dramatically reduced and should resolve hammering of weaker GPUs.
The cross-GPU resource sharing was fixed for Intel GPUs
You can now also set LUTs borders, and other custom textures in BGFX. Transparency can also be enabled so when combined you can do things like this:
Coming Soon
Vulkan renderer (with Linux release)
Native SteamDeck/Linux support

BGFX is a new mode for Borderless Gaming that captures game windows at the compositor level and processes them through a GPU effect pipeline. If you can see it on screen, BGFX can capture it and upscale it.
100% game compatibility
Games that never worked with BorderlessGaming, like Dishonored, titles that reset after being made borderless, or anything with unusual window handling—now work.
Built-in upscaling
Run games at lower resolutions, upscale to native. We ship FSR, NIS, GSR, Anime4K, NNEDI3, RAVU, and dozens more. Works on any content; games, video, anime.
History and feedback
Effects can access up to 7 previous frames and their own prior output. Build temporal AA, motion blur, accumulation effects.
Mouse input
Effects can read cursor position and clicks. Build effects that respond to where you're looking.
Window mode
Render to a separate window instead of fullscreen.
Background effects
Fill letterbox/pillarbox areas with blurred content, gradients, or ambient lighting instead of black bars without an app container.
[/hr]
Other changes
Window detection is now instant
Lower memory and CPU usage
Shader cache speeds up effect loading
Creating presets
Presets are JSON files (.bgfxp) that chain effects together. You can create them through the UI:
Or manually by writing them and dropping them into the presets folder in your data directory.
[c]{[/c]
[c] "version": 1,[/c]
[c] "name": "My Preset",[/c]
[c] "category": "Upscaling",[/c]
[c] "passes": [/c
[c] {[/c]
[c] "effect": "FSR/FSR_EASU.hlsl",[/c]

[c] "parameters": {[/c]
[c] "sharpness": 0.87[/c]
[c] }[/c]
[c] }[/c]
[c] ][/c]
[c]}[/c]
Each pass runs an effect. Set scalingType to control output size: Normal (use scaleX/scaleY multipliers), Fit (fit to display), Fill (fill display, may crop), or Absolute (fixed pixel size). Override effect parameters by name in the parameters object. Check the included presets for examples.
Writing your own effects
BGFX documentation is in the Effects folder. Effects are HLSL with header directives. Write a function that takes UV coordinates and returns a color; BGFX generates the compute shader dispatch code.
This architecture exposes the zero-copy renderer internals directly. Slang shader support and ML model integration (for BGUS upscaling and BGFG frame generation) are planned for the next minor release. They will be free content updates.

This update brings multi-language support, a new compatibility mode for troubleshooting stubborn games, and several quality of life improvements.
Multi-Language Support
Borderless Gaming now supports multiple languages (again)! The entire UI has been localized in 31+ languages and language files are easily customizable. If you want to contribute a new language, join the Discord.
Compatibility Mode
Some games use non-standard window handling that doesn't play well with modern borderless techniques. I've added a Compatibility Mode that replicates the exact window manipulation behavior from the original Borderless Gaming. How it works:

Launch Borderless Gaming with the --compat command line argument
The title bar will show "[COMPAT]" to indicate you're running in compatibility mode
Uses legacy-style window style removal and positioning that some older games expect
When to use it: If a game works in compatibility mode but NOT in normal mode, please let me know! Report the game on Discord or Steam Discussions so I can investigate and potentially add native support for that game's window handling quirks.
Profile Pinning & Sorting
Managing lots of profiles is now easier with new organization features.

Pin Profiles - Right-click any profile to pin it. Pinned profiles always appear at the top of your list
Smart Sorting - Profiles are now sorted alphabetically, with pinned profiles grouped at the top
Visual Indicators - Pinned profiles show a pin icon for easy identification

Improved Monitor Detection

Better Fallback Logic - If monitor detection fails, the app now gracefully falls back to the primary monitor
Enhanced Logging - More detailed logging for monitor retrieval helps diagnose multi-monitor issues
Improved Reliability - Fixes edge cases where monitor info could fail on certain display configurations

Technical Improvements

[/hr]
A Note on Compatibility Mode
The new compatibility mode exists because modern Windows and game engines have evolved significantly since the original Borderless Gaming was written. The new default behavior works better with most games, but some older or quirky titles expect the exact sequence of Windows API calls from the original version. If you find a game that:

Works with --compat flag but not normally
Has visual glitches in normal mode but not in compat mode
Crashes or behaves strangely only in one mode
Please report it! Include the game name and what happens in each mode. This helps me improve the default behavior so fewer people need to use compatibility mode.

Borderless Gaming v1.0.23

Hey friends, This update fixes some issues introduced in our last two releases. My attempt to fix older Unreal Engine games inadvertently broke newer ones. Rather than playing cat and mouse trying to make everything work automatically, I've added these parameters directly to the interface, giving you full control over which fixes and behaviors to apply. To apply any fixes to older Unreal games, you'll need to enable 'Flip Processing Order' in your game profiles. This setting is also applied by default to all Game Maker games
⚠️ Important: Unreal Engine Games
If you apply a profile with incorrect settings to an Unreal Engine game and it fails to go borderless properly, you MUST restart the game for any profile changes to take effect. Older Unreal Engine games store their window state in memory, which can cause issues when switching between different profile settings. Simply changing the profile while the game is running won't work - a full game restart is required.
Profile Examples
LET IT DIE:

'Preserve Client Area Size' - Maintains correct internal resolution
'Send Maximize' - Properly expands the game window width
'Nudge Window' - Expands height to cover the taskbar area (works whether taskbar is hidden or visible)
Dishonored: This game doesn't support window nudging. You only need:

'Send Maximize' + 'Flip Processing Order'
Borderlands: Works well with minimal configuration - just enable:

'Flip Processing Order'
Gears of War: Reloaded: Newer Unreal Engine game that needs:

'Preserve Client Area Size' + 'Send Maximize' (no 'Flip Processing Order' needed)
Additionally, I changed the default hot key for hiding task bar to Ctrl+Shift+L
Important Notes

Every game behaves differently, so experiment with your profile settings if the defaults don't work
Remember to restart Unreal Engine games after changing profiles if they're not working correctly
To make this easier, I'm adding Steam Workshop support in version 1.1 so you can share working profiles with the community!

Key Fixes:

Resolves issues with older Unreal Engine games that historically haven't worked with Borderless Gaming (see details below)
Fixes profiles for certain Unity and Google Play on PC games
Corrects state synchronization issues in foreground tracking
Unreal Engine Compatibility Many Unreal Engine 3 games from the 2010s were never designed with windowed mode in mind. As a result, each game responds differently to being resized or moved while in windowed mode, and even fewer support dynamic resizing. This update implements a new strategy that successfully enables Borderless Gaming functionality for these problematic titles. However, since these older games behave differently despite sharing the same engine, no single profile configuration will work universally. Example 1: LET IT DIE Recommended profile settings: LET IT DIE properly detects when the display's working area changes and adjusts its height to fill the space left by the taskbar. It also handles dynamic taskbar restoration smoothly. The "Preserve Client Area" option should be enabled because while the game doesn't initially know how to handle window maximization, after the initial positioning it maintains borderless fullscreen without the window constantly resetting (avoiding the repeated brute-force adjustments that Borderless Gaming would otherwise apply). Example 2: Dishonored Recommended profile settings: Until now, achieving true fullscreen with Dishonored (without mods) has been impossible. This is because the game completely resets its size and window styles whenever the window is moved, making borderless mode nearly impossible to maintain. Unfortunately, it also resets when the taskbar is dynamically restored. Therefore, the best approach for Dishonored is to hide the taskbar to preserve the borderless fullscreen state. Note: If the default settings don't produce the desired results for your specific game, we recommend experimenting with different profile options until you find the combination that works best. Each game may require unique settings to achieve optimal borderless fullscreen performance.

Dark Mode is Now Free
When I initially released the dark mode DLC it was done to fund the rewrite of Borderless Gaming and the creation of the upcoming upscale / frame generation features. With the rewrite done, I believe the dark mode DLC has served its purpose. Despite its good intentions, based on the constant wave of negative reviews around it, just isn't worth having it available anymore as an optional DLC. So the DLC is being retired. Dark mode is now part of the base product. I'll be putting up a website that allows you to get early access to the new features (BGUS/BGFG) before everyone else if you previously purchased dark mode.
